How Cooking Made Us Humans By Richard Wrangham

Good Essays

Cooking is a vital, overlooked component necessary to accomplish every human’s basic fundamental needs to survive and reproduce. According to Maslow’s hierarchy of needs, food is one of the factors that constructs the base of the pyramid’s physiological section (Myers 330). This section cannot be considered without its fundamental component, the act of cooking. Not only is this act executed in most human individuals’ everyday lifestyle, but has also increased their fitness in the course of time. In Catching Fire: How Cooking Made Us Humans by Richard Wrangham, Wrangham similar idea convinces me. Wrangham declares that it was fire and cooking that led to new crucial physical traits developed in humans. Whether fire was created as a …show more content…

Studies such as Peter Lucas experiment incorporated into the passage supports this claim and Wrangham’s concept that it was cooked food that led to a change in external and internal human body structures. In Luca’s study, he “calculated that the size of a tooth needed to make a crack in a cooked potato”. His results demonstrated that the size of a tooth that is needed to perform this task “is 56 percent to 82 percent smaller than needed for a raw potato”(Wrangham 43). This gives an explanation as to why humans have miniature teeth compared to other animals whose diets consists mainly of raw food compared to humans and elaborates how the tooth structure optimizes it function. In this case, because not a lot of force is needed to chew tender cooked food, having large tooth would not provide any extra advantages to Homo Sapiens and is one of the reasons that a human’s physical mouth appearance is smaller when compared to past common ancestors. This would rather make humans have too complex organs without any advantages to their survival or reproduction.
Additionally, the jaw muscles: masseter, temporalis, medial pterygoid, and the lateral pterygoid are involved in mechanical digestion. The change of tooth size also influenced the jaw muscles’ length. The primary function of the jaw muscles is to aid the process of breaking down food into smaller particles to make food digestion more effortless. As the size of teeth decreased, the amount of
